New taxa of Laparocerus Schönherr, 1834 from Madeira and Porto Santo, with a key to the species of the Madeiran archipelago (Coleoptera, Curculionidae, Entiminae)

Abstract

As part of a monographic study of the weevil genus Laparocerus Schonherr, 1834, which is very diverse in Macaronesia, this paper proposes some changes to the systematics of the genus and describes a number of new taxa from the archipelago of Madeira. Combining the morphological data with the molecular data presented in a previous contribution, the subgenera Laparocerus and Atlantis are redefined and three new subgenera are described: Atlantodes n. subgen., Pseudatlantis n. subgen. and Wollastonius n. subgen. In addition, six new species from Madeira are described: L. madeirensis n. sp., L. hobbit n. sp., L. serrado n. sp., L. silvaticus n. sp., L. stuebeni n. sp. and L. prainha n. sp., as well as L. cryptus n. sp. from the Ponta de Sao Lourenco, Porto Santo and Deserta Grande. A key to all known Laparocerus from the archipelago of Madeira is provided.
